[Pkg-octave-devel] Bug#710272: Bug#710272: octave: Printing gives a Ghostscript error
Hi,
running the code
octave:1> set (0, "defaultaxesfontname", "Helvetica")
octave:2> x = linspace(0, 10);
octave:3> plot(x, sin(x));
octave:4> print -dps2 plot.ps
works. The PostScript file is produced as desired.
Without setting the font this fails. When I execute this
octave:1> x = linspace(0, 10);
octave:2> plot(x, sin(x));
octave:3> print -deps2 plot.eps
an eps is created. When opening with Ghostscript I get the following error messages:
GPL Ghostscript 9.05 (2012-02-08)
[...]
Loading StandardSymL font from /usr/share/fonts/type1/gsfonts/s050000l.pfb... 3527728 2097376 4600464 3242420 2 done.

GPL Ghostscript 9.05: Unrecoverable error, exit code 1
I had the fonts-pagul package installed. When I remove the package the error is gone. Nerver the less, when opening the created _EPS_ file with Ghostscript I get the following warning:
GPL Ghostscript 9.05 (2012-02-08)
[...]
Can't find (or can't open) font file /usr/share/ghostscript/9.05/Resource/Font/{}.

Didn't find this font on the system!

Thus I think that octave or gnuplot (to answer the question: Yes I am using the gnuplot backend.) somehow create an invalid EPS file.
Kind Regards,
Hendrik

Hi,
I tried to reproduce the error on another Debian testing machine, but I
was not able to do so. At the moment I do not have access to the machine
with the error. However I will test tomorrow if setting the default font
fixes the problem.
>From what I remember: A postscript file is generated that can not be
viewed in Evince, Okular oder Ghostscript. When opening with Ghostscript
I got the error that it could not find the font file
/usr/share/ghostscript/9.05/Resource/Font/{}
Thus this sounds pretty much like what is described in your reference
[1].
Kind Regards,
Hendrik
